Title: Leak detection device
Inventor: SUYAMA KIICHI
IPC: G08B21/16
Filed: 1994-11-01
Abstract: PURPOSE: To make it possible to detect the existence of leak from the supply pipe of fluid such as gas or the like automatically so as to require no hand for inspection. CONSTITUTION: A supply pipe 11 is composed of two portions, that is, an underground buried portion 11a and a ground arranged portion 11b in the vicinity area of a downstream side gas meter. When a flow quantity detected by a flow meter 16 becomes a very small quantity less than a predetermined flow quantity (a pilot flame flow quantity), a shut-off valve (V1) 12 and a shut-off valve (V2) 15 are respectively brought in a closed state. Thereafter, the existence of the leak of the supply pipe 11 in an area from first spot A to second spot B is judged based on the detection result of a pressure sensor (P1) 14 and the existence of the leak of the supply pipe 11 in an area from the second spot B to third spot C is judged based on the detection result of a pressure sensor (P2) 17 is detected at the same time.

IPC: G01N1/22
Filed: 1987-11-18
Abstract: PURPOSE:To make the title apparatus small-scale and to allow the same to correspond to transient running, by mutually connecting two large and small venturi means to a gas flow passage through which a sample gas flows. CONSTITUTION:A sample gas G is divided into venturi means 5, 6 and the gas G through the small venturi means 6 flows in a diluting gas flow passage 8 and is mixed with the air (g) from a filter 9 in a dilution tunnel 10 to receive predetermined dilution. This diluted gas G is divided on the downstream side of the tunnel 10 and the gas G flowing in a gas sampling flow passage 12 reaches a particulate collecting filter 15. Since the particulate contained in the gas G is caught by the filter 15, the weight difference of the filter 15 before and after the collection of the gas G is calculated and multiplied by a predetermined multiple to make it possible to obtain the total amount of the predetermined gas component in a gas flow passage 4. At this time, the gas is divided in a predetermined flow dividing ratio by a constant flow rate apparatus 11 and the flow passage 12.

Abstract: PURPOSE:To continuously filter over a long time while satisfying required bacteria removing ratio by laminating the plural numbers of a film having an average pore diameter not smaller than a specific value and the specific range of lactic acid bacteria removing ratio LRV. CONSTITUTION:The plural numbers of the film having >=0.7mum average pore diameter and 0.6-3 LRV to lactic acid bacteria are laminated to filter beer. The removing ratio of lactic acid bacteria is gradually decreased with the increase of the pore diameter of the film and the other hand, the clogging rate of the film due to the filtration of the beer is rapidly reduced. Though the lactic acid bacteria removing ratio LRV of the film is <=3 in 0.8-1mum average pore diameter of the film, by laminating two or more numbers of the film to use, the LRV of >=5 is attained. On the other hand, the clogging rate is not so much reduced even when plural numbers of the film having larger pore diameter are laminated to use. Then, the required LRV is attained and a large filtration capacity is obtained.
